thereon, which form a part of this specification.

This invention relates to hydraulic motors, or motors which utilize thegravity of water or other fluid media as the impelling force or powermedium, and vertically-reciprocating carriers as the recipients of suchmedia, which is supplied to each alternately at their highest point oftravel. The carriers, generally two, are connected to travel in oppositedirections, the one elevating while the other is lowering, and viceversa. While one carrier is loading the other is unloading, each beingheld in its relative position by a weighted lever or equivalent meansuntiltheIoneloadinghas received a given weight, when it willautomatically dis engage itself and descend, at the same time liftingthe other carrier into position to receive its load. The carriersdischarge their load in a less time than it takes to load them; hence itis expedient to devise a means to hold the carrier being loaded until ithas received a given weight. The bottom of each carrier is provided witha discharge-opening for the escape of the iluid medium, which is closedby a valve, and that this valve may not be held down by a too greatpressure of the water its top extends to the top of the carrier, orthere about, and its sides are approximately paral lel, or converge veryslightly, so that the war tcr may exert sufficient pressure thereon tohold it down on its seat. The weighted lever for holding the carrier atits highest position is provided with a pivoted catch or detent, whichturns up out ot the way when the carrier is rising and falls back in thepath of the said carrier, or a portion thereof, to engage therewith andprevent the descent of the car- 0 rier until properlyioaded. The powermay be (No model.)

transmitted from either or both of the carriers directly or by means ofintermediate connections. A

The improvement consists of the novel features hereinafter more fullydescribed and claimed, and shown in the annexed drawings, in which-Figure l is a side view, parts being broken away, ofa motor of myinvention; Fig. 2, an end view of the motor, showing the side of thecarrier removed; Fig. 3, a top sectional view on the line XX of Fig. l,the weighted levers and their supporting-brackets being removed; Fig.4,a detail side view of the weighted lever,showing the operation of thesame; and Fig. 5, a 6 side View of a modified form of weighted lever.

The frame is composed of the corner posts, A, bottom side and end sills,B and B, respectively, and top side and end beams, G and C,respectively. The frame is braced by the stays a and a, which areinterposed be tween the side end sills, B and B, and the corner posts,A.

The carriers or buckets D and D, located in different vertical planes,are adapted to travel vertically, being guided in their move ments bythe guidebars E, which are interposed between the beams C and the sillsB, and pass through the guide-bearings e, secured to the sides of thesaid buckets or carriers, which may be of any suitable dimensions andform. Each bucket or carrier has a discharge-opening, f, in its bottom,which is closed by a valve, F, which extends to about the top of thebucket or carrier and has its sides nearly parallel. The edges of thevalve are provided with eyebolts g at different levels, which embracethe vertical guide-bars G, extending up from the bottom of the carrieror bucket to guide the said valve in its verti- 0 cal movements. Thesides of the valve converge slightly near the upper portion of the saidvalve to receive a certain percentage of pressure of the fluid to holdthe said valve down and overcome in part the buoyancy of the fluidthereon. The carriers or buckets are connected together by the chain orcable (I, which passes over a pulley, h, keyed to the shaft H, mountedin bearings on the top of the frame. The gear-wheel i, secured to theshaft H, meshes with and imparts motion to the rack-bar I, whichtransmits said motion to the desired machine, which, as shown, is thepump J, one being located at each end of the rack-bar or piston-rod.

The trough K,'for holding the water or other fluid to be supplied to thebuckets or carriers, is located on the frame, and has openings in itsbottom corresponding to the position of the said carriers or buckets Dand D, that are closed by valves L, constructed similarly to the valvesF, and guided in their vertical movements by the eyebolts Z and theguiderods Z above the bottom of the trough, and by the stems Z and thetruss-bar Z below the bot tom of the trough. The stems Z that dependfrom the valves L, project some distance be low the truss-bars Z, andare adapted to be struck by brackets M, secured to the sides of each ofthe carriers or brackets D and D by the bolts m, to unseat the valve andpermit the fluid to escape into the bucket or carrier, whichever one maybe at its highest elevation.

The several valves F and L are made of wood, and the lower edge of eachis provided with a band, a, of metal, rubber, or leather, which forms aconcavitybelow the valve and insures a close fit between the lower edgeof the band and the bottom of the trough. The valves F are each providedwith a rod, N, that extends up through a bracket, 0, secured to the beam0, and is provided with an adjustable stop, it, to regulate the distanceof movement of the valve when lifted from its seat. The rod N worksfreely through 0, and when the carrier or bucket settles or descends thestop a, engaging with 0 just before the said bucket reaches its lowestposition, unseats the valve and allows the load or fluid to escape.

The weighted levers Pone for each bucket or carrierare constructedalike; hence a de scription of the construction and operation of onewill suffice for both. The lever P,having a horizontal arm, 1), and avertical extension, 19', is pivoted to the depending bracket Q at thepoint of junction of p and p. The catch or detent R, pivoted to thelower end ofp, is adapted to stand out from 1) either at an acute angle,Fig. 4, or a right angle, Fig. 5, being held in such position by ashoulder or extension, 1', abutting against. a corresponding shoulder orextension, r, of p. The end of R normally projects within the path ofthe carrier or bucket or an extension, 1), thereof to engage therewithand hold the bucket or carrier while being loaded, and is adapted toturn up out of the way when the carrier is ascending, so as not toimpede its movement or detract from the force of the descending bucketor carrier. When the bucket or carrier has risen, the detent or catch Itgravitates and automatically falls within the path of the bucket or itsextension I) and holds it elevated until sufficiently loaded tooverbalance the weight P on P, when P turns on its pivot and disengagesR from the said bucket or its extension, when the said bucket willdescend. The catch is so disposed that it will not fold too close to soas to bring the center of gravity over its pivotal support, but just.enough to permit the bucket or carrier to clear it when rising and havethe center of gravity thereof to one side of said pivotal support, so Rwill automatically fall back within the path ofthe said bucketor'carrier or its extension. To prevent R folding too close, especiallywhen struck quickly, it has been found expedient to provide 1) with astop, f, for R to strike against and limit its upward movement. Theweighted lever]? is held in a normal position by the stirrup P, whichsupports its horizontal branch and permits it to rise when P isoverbalanced.

The weight P being adjusted on P according to the work to be performed,and K being supplied with a fluid medium, the motor is in readiness tooperate, which is accomplished. by elevating one of the carriers orbuckets until it is held by the weighted lever. The bracket M, strikingP, will have opened the valve in K, and the medium from K escaping intothe said bucket will weight it, and when the weight of the bucket orcarrier is in excess of the weighted lever said bucket or carrier willautomatically disengage itself from P and descend, and just beforereaching its lowest position n will engage with O and lift F anddischarge said load. During the descent of said bucket the correspondingbucket is rising, and when the one is unloading the other is loading.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is-

1. In a water-motor, the combination of the tank having openings in itsbottom, the valves extending about the full height of the tank andhaving the edges parallel and the sides slightly converging, the stemsdepending from the valves, the two carriers connected together andadapted to reciprocate alternately in a vertical direction and strikeagainst the said stems, and the two weighted levers adapted toalternately engage with the carriers and hold them while the one isloading and the other is unloading, substantially as and for the purposespecified.

2. The combination, with the counterbalancing carrier or bucket and thevalves F, of the brackets O, the rods N, and the adjustable stops n,substantially as and for the purpose described.

In testimony whereof I affix my signature in presence of two witnesses.

JACOB VVILHELM.
